SuperKernel

This: https://www.forum64.de/index.php?thread/74462-projekt-superkern..

I’ve gotten reports that EotB crashes when this is used together with EasyFlash3. The game boots but can’t get past the intro.

I don’t use kernel routines other than the $0314/15 vector. At this point in the game all EF3 setup is done and I only do bank switching via $de00.

They have ”disabled” the SuperKernel.

Ideas?

Quote: Because you can’t swap out kernel and not swapping out the cart in 16kb mode. See https://www.c64-wiki.com/wiki/Bank_Switching (last modes where exeom and game = 0)

16kb or not. If you want cart rom you’re stuck with kernel always with the exception of ultimax.

Indeed and one wonders how they fail to not fuck up $fffe/ffff and the kernel main ISR. Maybe they didn’t and it’s a HW glitch.. *shrugs*

If it reliably crashes at the same point, i wouldn't rule out a software-side fix without investigatin'. :)

Exactly. He’ll come to X. I’ll do some investigatioms there.

My guess:

There may be small spikes on the KERNAL selection lines which cause the MCU to serve KERNAL data for much longer than the original ROM did (if it did at all) for these false triggers. The GAME/EXROM combination used might make it worse.

http://sleepingelephant.com/ipw-web/bulletin/bb/viewtopic.php?t..

It's not something I'd worry to much to work around. This setup is probably broken due to the replaced KERNAL ROM.

Btw. it might be worth to see if the EF3 external KERNAL replacement function is enabled or not, that could cause some extra trouble as well (more spikes due to how it works).

Not sure if the KERNAL replacement and an EF slot can be active at the same time in the first place. In EF3 I mean.

EF3 clearly states that it shouldn’t be used with expanders, but I suppose all cart manufactorers say that.

I think Soci’s explanation is plausible.

NO cartridges should be used with expansion port expanders. ever. the port is not designed for it, you are asking for trouble.

What I meant was that I'm not sure if it is possible to activate EF3's KERNAL replacing functionality and one of its EF slots at the same time. At least the user interface doesn't imply it would be possible; from the menu you can launch a KERNAL, freezer or EF slot.

I'm using a SuperKernal with 1541Ultimate II+ (U2p), this is working well for me. But you can't use the external kernal replacement of the U2p, this gives a black screen and C64 doesn't come up. Should be same with EF3.
